Development of selection system for levitated nano-particle using photo-thermal effect

描述了光驱动方法在抗磁材料数值分析和实验中的应用。该系统由永磁体、温敏铁氧体和光源组成。由于抗磁性材料可以被动悬浮，因此可以无接触地高效驱动。温敏铁氧体的磁化率取决于其光热效应控制的温度。加热温度敏感型铁氧体可以改变磁通分布。因此，可以在无接触的情况下控制抗磁性材料。通过一维和三维数值分析，得出了抗磁材料非接触光驱的可能性。结果，用烙铁代替光成功地控制了抗磁性材料。

This application is described light-driven method for diamagnetic material in numerical analysis and experiments. The proposed system consists of permanent magnets, temperature-sensitive ferrite and light source. Since diamagnetic material can levitate passively, it was driven efficiently without contact. Magnetic susceptibility of temperature-sensitive ferrite depends on its temperature controlled by photo-thermal effect. Magnetic flux distribution changes by heating temperature-sensitive ferrite. Therefore diamagnetic material can be control without contact. Noncontact light-driving possibility of diamagnetic material is derived from numerical analysis in one and three dimension. As a result, diamagnetic material is successfully controlled by using soldering iron instead of light.
